Important: The value of a reserved bit must be maintained in software. When you modify registers containing reserved bit fields, you must use a read-modify-write operation to preserve state and prevent indeterminate system behavior.

8 | rst |
Jtag rst signal. Test reset—will asynchronously reset the JTAG test logic. The logic is reset {with TRST} regardless of the state of TMS or TCLK. (Asynchronous) (Active low reset) |
RW | 0x1 |
7:0 | id |
JTAG ID used to provide each HP PLL IP a unique ID. |
